Abstract
An image forming apparatus includes a plurality of rotors, and an endless belt that is supported with tension by the plurality of rotors and rotated by the rotors. Herein, at least one of the plurality of rotors is provided, at a first end, with a belt restraining member that has a restraining face for restraining displacement of the endless belt toward the first end and that is rotatable with respect to the rotor; and the belt restraining member is arranged such that an angle between the restraining face of the belt restraining member and a rotation shaft of the rotor is greater at a contact start point at which the endless belt begins contact with the belt restraining member during rotation than at a contact end point at which the endless belt ends contact with the belt restraining member during rotation.
